T=2A+4
S=5A-8
If Tom and Sara are 10 years old,
10=2A+4
6=2A
3=A
Not sure though

Andrew= 4 years old
Sara= 12 years old
Tom= 12 years old
Basically, I did guess and check. First I started with Andrew 10 years old. I kept going down until I reached Andrew as 5 years old. I went 1 number down to 4 and that was perfect because that way Tom and Sara had the same age.

A cylindrical Is half full of oil The cylinder Has a base radius of 100 cm The height of the cylinder 250cm 1 litres = 1000cm3 H

Softa [21]

Answer:

V=3926.99 liters

Step-by-step explanation:

cylindrical Is half full of oil The cylinder Has a base radius of 100 cm The height of the cylinder 250cm 1 litres = 1000cm3 How many litres of oil are in the tank?

Volume of a cylinder can be calculated using below formula

V=π r^2 h

Where r= radius

h= height

radius = 100 cm

h=250cm

But the cylinder is half filled, then the formula becomes

V=(π r^2 h) × 1/2

Then substitute the values we have

V=( π × 100^2 ×250) × 1/2

V=3926990 cm^3

But 1 litres = 1000cm3

Then V=(3926990 cm^3)/ 1000

V=3926.99 liters

Which equation below does NOT represent a function of X A) x=y^2 B) y=x C) y = |x| D) y=x^2 E) y=1

vlabodo [156]

Answer:

A) $x = y^{2}$

Step-by-step explanation:

An equation is a function of $x$ when $x$ is the independent variable, that is:

$y = f(x)$ (1)

Where $y$ is the dependent variable.

According to this, $x = y^{2}$ does not represent a function of $x$ , since the independent variable is a function of $y$ , that is, $x = f(y)$ . Therefore, the correct answer is A.
